Question

3(k-5)+2k= 4k +7
i need the asnwer to this please

Answer 1

Answer is k= 22

Step by step.

First we do distribution of numbers in parentheses. Multiply 3 (k-5).

3k -15 +2k = 4k + 7.

Next we isolate “k” by moving numbers to one side of the = sign. We do this by doing the opposite sign on both sides, shown with { }

3k -15 {+15}+ 2k = 4k + 7 {+ 15}

3k + 2k = 4k + 7 + 15

Now we need to get variables to one side the same way.

3k + 2k {-4k} = 4k {-4k} + 7 + 15

Now combine like terms

1k = 22
k = 22
